The answer to youre question Abodybomber is yes iam testing the waters I have a 440 1969 cast number-2536430-6-R/B if that means anything shes a virgin which is a myth and forbidden word around these parts,anyway back to the block virgin bores was going to throw the crank back in standard rods new piston rings bearings the standard pistons are still ok,new oil pump water pump gaskets etc.a voodoo roller cam PN-60312
roller rockers roller lifters rpm manifold and latter on when family kids allow for some alloy heads.Just looking down different roots to take,the cam interchange question was for a mates 400 hes putting in his rat rod he has a cam for a 440 but was unsure about changeability yes it would have to be a 3 bolt for the peter Jackson drive gear that he has for her,Thanks for youre input guys all of you its fantastic knowledge,
